NGC 3718 and NGC 3729

NGC 3718 (left) and NGC 3729 (right) are two related galaxies in the constellation of Ursa Major at a distance of 42 million light years. Gravitational interaction caused the disk of NGC 3718 to be strongly warped, which results in the S-shaped appearance. The galaxy-group above NGC 3718 is Hickson 56 at a distance of roughly 425 million light years.

This is the first-light image of my participation at Blackbird Observatory, Sierra Remote (California), taken by our half-meter RCOS telescope.
